I like the Murf one

I created a patch sheet for the VX-351 and CP-251 in just a simple excel file. I didn't use too many diagrams and opted for a comments/notes section so people could just write down destinations as I felt diagrams would get messy drawing patches between the units. It's in Squarewave if anyones wants a look. I wonder if anyone uses it?
Never forget the power of your digital camera

Just take a picture of that patch setting and your good to go.
